Silicon forms what is known as a network covalent solid. Most covalent compounds that involve a couple atoms bonded together to form a molecule, and those molecules attracted to each other through weak intermolecular forces. Because these forces are relatively weak (compared to covalent or ionic bonds), molecules are easily separated from each other and so covalent compounds typically have low melting points. Silicon atoms are different. They form huge networks of strong covalent bonds with each other, essentially making huge molecules with atoms that are not easy to separate. A great example of another network covalent solid is a diamond (carbon atoms bonded together in a huge network). So if you look at a diamond you are essentially looking at one huge molecule--all the atoms covalently bonded together.

Silicons melting point?
The melting point of silicon is 1414 degrees Celsius (2577 degrees Fahrenheit). At this temperature, silicon transitions from a solid to a liquid state.
Is the melting point for methanol higher than silicon?
No, the melting point of silicon is higher than methanol. Silicon has a melting point of 1414°C, whereas methanol has a melting point of -98°C.
At which temperature silicon melts?
Silicon has a melting point of 1414°C (2577°F).
What substance has higher melting point silicon dioxide or methanol?
Silicon dioxide. Silicon dioxide silica is the mineral quartz and is a giant molecule with a melting point of over 16000C. Methanol is a molecular compound (an alcohol) with a melting point of -980C
What silicons melting point?
The melting point of silicon is 1414 degrees Celsius (2577 degrees Fahrenheit). Silicon is a crystalline solid at room temperature but transitions to a liquid state above its melting point.
Is silicon dioxide volatile?
Silicon dioxide is not volatile. It has a high melting and boiling point, making it a stable compound at room temperature.
Silicons melting point?
The melting point of silicon is 1414 degrees Celsius (2577 degrees Fahrenheit). At this temperature, silicon transitions from a solid to a liquid state.
Does silicon have a high melting point?
Yes, silicon has a high melting point of 1414 degrees Celsius. This high melting point is due to its strong covalent bonding structure in its crystalline form.
What element has the highest melting point magnesium silicon or chlorine?
The element with the highest melting point is silicon. Silicon has a melting point of 1414°C, while magnesium melts at 650°C and chlorine is a gas at room temperature.
Do metalloids always have high melting temperatures?
No, metalloids do not always have high melting temperatures. While some metalloids like boron and silicon have relatively high melting temperatures, others like arsenic and antimony have lower melting temperatures. The melting temperature of a metalloid depends on its specific atomic structure and bonding characteristics.
Is the melting point for methanol higher than silicon?
No, the melting point of silicon is higher than methanol. Silicon has a melting point of 1414°C, whereas methanol has a melting point of -98°C.
At which temperature silicon melts?
Silicon has a melting point of 1414°C (2577°F).
What substance has higher melting point silicon dioxide or methanol?
Silicon dioxide. Silicon dioxide silica is the mineral quartz and is a giant molecule with a melting point of over 16000C. Methanol is a molecular compound (an alcohol) with a melting point of -980C
Is silicon a solid liquind or gas?
Silicon is a solid at room temperature. It has a high melting point of 1414°C and a boiling point of 3265°C, so it exists as a solid in most everyday conditions.
What silicons melting point?
The melting point of silicon is 1414 degrees Celsius (2577 degrees Fahrenheit). Silicon is a crystalline solid at room temperature but transitions to a liquid state above its melting point.
Why is silicon a suitable material for lining furnaces?
Silicon dioxide is suitable for lining furnaces because of its very high melting point of 1,600 to 1,725 degrees celcius. It is so high because of the strong intermolecular forces between SiO2 molecules in the giant covalent structure comparable to that of diamond and graphite. A large amount of energy is required to overcome these intermolecular forces and thus SiO2 has a high melting point. Note: no silicon-oxygen bonds are broken during melting, just intermolecular forces between SiO2 molecules.
Why silicon is prefer in semiconductor as compare to germanium?
Silicon is preferred over germanium in semiconductor applications because it has a higher melting point, better thermal stability, and can form a native oxide layer for insulation. Additionally, silicon has a wider bandgap, making it more suitable for high-temperature and high-power electronic devices.
